Tools

• catalogue_stats

  Size and health of the x402 catalogue as of the latest full scan: resources, hosts, verdict counts, and payable endpoints per network.

  shallow
• drift_status

  Verdict changes between the two latest full scans (catalogue wide, or for one host), plus the declared model drift watch.

  shallow
• find_endpoints

  Search the catalogue by host or URL substring. Returns up to `limit` endpoints with their latest verdict, plus the total match count. Use this first when you do not know the exact resource URL. Optional network filter (for example eip155:8453 or solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp) and sort=price for the cheapest first.

  shallow
• host_summary

  Summary for a host (no time series): first/last seen, current verdict mix, n_resources, total verdict changes, gone_since if absent from the latest full scan, and a small resources_sample.

  shallow
• payability_verdict

  Latest payability observation for one exact resource URL (path and query included), with the meaning of the verdict, remediation if it cannot be paid, and the per-network options seen.

  shallow
• reports

  Published weekly payability reports (from the signed manifest).

  shallow
• verify_signature

  Offline EIP-191 verify of a signed nsgoods response. Identifies the service from the manifest (or the optional `service` arg), strips exactly that service's post-sign fields, canonicalises (JCS, both ASCII modes), recovers the signer and checks it against the published manifest signers. Reproduction-attestation (JCS/byte-length) and envelope (signer/signature, components) shapes are reported as unsupported_shape, not verified here. Refusals carry a distinct status: malformed_signature (signature is not a 65-byte 0x-prefixed hex string), schema_rejected (the body carries a signed_by/signature pair but fails the required field shape for every service the claimed signer covers; recovery was not attempted, checked is false, reasons lists the failed candidates), signature_mismatch (well-formed but recovers a different address than signed_by under every candidate service recipe of this signer), no_flat_recipe (signed_by is a manifest signer but every service it covers uses an envelope shape, so there is no flat recipe to check; recovery was not attempted, checked is false), unknown_signer (signed_by is not a manifest signer; recovery was not attempted, checked is false), unsupported_shape, or the no-signed_by/signature-pair case. checked is true only when EIP-191 recovery actually ran; every other refusal reports checked false.

  shallow
• x401_status

  Current x401 emitter adoption across the scanned catalogue (from the daily watcher).
